ORGANIC OPTOELECTRONIC DEVICE, AND DISPLAY DEVICE INCLUDING SAME

摘要

The present invention relates to an organic optoelectronic device and to a display device including same. The organic optoelectronic device includes a positive electrode, a negative electrode, and one or more organic thin film layers formed between the positive electrode and the negative electrode. The organic thin film layer has a light-emitting layer, a hole transport layer, a hole injection layer, an electron transport layer, an electron injection layer, or a combination thereof. Also, said organic thin film layer has a light-emitting layer and a plurality of hole transport layers. One of the plurality of hole transport layers adjacent to the light-emitting layer contains a compound which is represented by a combination of chemical formula 1, chemical formula 2 or chemical formula 3, and chemical formula 4. One of the hole transport layers not adjacent to the light-emitting layer contains a compound represented by chemical formula B-1.
